INTRODUCTION
The 7139CS/CSX & 7139LS smoke alarms are photoelectric
type alarms for use as an evacuation device in residential
applications, while the 7109CS/CSX & 7109LS are for use as an
alert and relocate device. Each smoke alarm has a solid state piezo
signal to warn and alert the household to the presence of threatening
smoke.
Your photoelectric smoke alarm is designed to detect the smoke
that results from an actual fire. Consequently, it is uncommon for
household smoke such as cigarette smoke or normal cooking smoke
to cause an alarm.
MODEL NO. DESCRIPTION
7109CS/CSX-W or C*.....120 VAC, 60 Hz with 1 Form C Aux. Relay
Contact and Visual Signaling Strobe Light
with Tandem Wire Connection. CSX model
is provided with an additional wire (grey)
for the remote activation of the strobe.
7109LS*.......................... 120 VAC, 60 Hz Wall Mounted, Provided
with a 9 ft. Line Cord, Pulsating Horn.
7139CS/CSX-W or C**....Same as the 7109CS but with a Temporal
Horn. CSX model is provided with an
additional wire (grey) for the remote
activation of the strobe.
7139LS**........................ Same as 7109LS but with a Temporal
Horn.
* These units produce a non-temporal audible alarm and are therefore
not intended for locations where the desired action of the occupant(s)
is evacuation.
** Per NFPA 72, the American National Standard Audible Emergency
Evacuation Signal as defined in ANSI S3.41, is required whenever
the intended response is to evacuate the building.
HOW YOUR SMOKE
ALARM WORKS
These smoke alarms operate on the photoelectric light scatter
principle. The unit's sensing chamber houses a light source and a
light sensor.
The darkened sensing chamber is exposed to the atmosphere
and designed to permit optimum smoke entry from any direction
while rejecting light from outside the smoke alarm.
The light source is an infrared (invisible) LED which pulses every
4-8 seconds. The light sensor is a photodiode matched to the light
frequency of the LED light source.
Under normal conditions, the light generated by the pulsing
infrared LED is not seen by the light sensor, as it is positioned out of
the direct path of the light beam. When smoke enters the sensing
chamber, light from the pulsing LED light source is reflected by the
smoke particles onto the photodiode light sensor. At the first sighting
of smoke, the smoke alarm is put into a pre-alarm mode. This is
indicated by a rapidly flashing LED on the face of the smoke alarm.
Once the light sensor confirms smoke for 2 consecutive pulses
inside the chamber, the light sensor produces the signal necessary
to trigger the smoke alarm.
This technique of verifying the smoke condition, combined with a
5-to-1 signal-to-noise ratio, substantially reduces the possibility of
nuisance alarms.
HOW TO TELL IF YOUR SMOKE
ALARM IS WORKING PROPERLY
Your smoke alarm is provided with an alarm horn and pulsating
Light Emitting (indicator) Diode, which pulses every 15-30
seconds, and a green AC power on LED.
When turning the test knob on the alarm to TEST 1, the red light
will flash rapidly, the horn will sound and the strobe will flash.
Strobe will not operate without AC power.
If the battery is low or missing, a chirp will be emitted when the
red LED flashes. If the smoke alarm is malfunctioning, the chirp
will sound between the red LED flashes. If AC power fails, the
green LED will turn off.
The test knob of your smoke alarm simulates actual smoke
conditions.
NOTE: Tandem Interconnect Models.
When testing one smoke alarm, the smoke alarm that is activated
will flash the red indicator light and sound its alarm horn. All
other units will sound the alarm horn with their red indicator lights
remaining off.
FIRE PROTECTION PLAN: WHAT
YOU CAN DO TO MAKE YOUR
FAMILY SAFE FROM FIRES
This smoke alarm can quickly alert you to the presence of
smoke-it cannot prevent fire. The ultimate responsibility for fire
protection rests solely on you.
Installing smoke alarms is just the first step in protecting your
family from fires. You also must reduce the chances that fires will
start in your home and increase your chances of safely escaping if
one does start. To have an effective fire safety program:
a. Install smoke alarms properly following the instructions
in this manual. Keep your smoke alarms clean. Test your
devices weekly and repair or replace it when it no longer
functions. As with any electronic product, smoke alarms have a
limited life, and devices that don't work cannot protect you.
b. Follow safety rules and prevent hazardous situations:
Use smoking materials properly; never smoke in bed.
Keep matches and cigarette lighters away from children.
Store flammable materials in proper containers and never use
them near open flames or sparks.
Keep electrical appliances and cords in good working order
and do not overload electrical circuits.
Pg. 7-1
PHOTOELECTRIC TYPE RESIDENTIAL SMOKE ALARMS FOR THE
HEARING IMPAIRED, AC POWERED WITH 9V BATTERY BACKUP
Keep stoves, fireplaces, chimneys, and barbecue grills grease-
free and make sure they are properly installed away from
combustible materials.
Keep portable heaters and open flames such as candles away
from combustible materials.
Do not allow rubbish to accumulate.
Do not leave small children home alone.
c. Develop a family escape plan and practice it with your entire
family, especially small children.
Draw and post a floor plan of your home and find two ways to
exit from each room. There should be one way to get out of
each bedroom without opening the door.
Teach children what the smoke alarm signal means, and that
they must be prepared to leave the residence by themselves if
necessary. Show them how to check to see if doors are hot
before opening them, how to stay close to the floor and crawl
if necessary, and how to use the alternate exit if the door is hot
and should not be opened.
Decide on a meeting place a safe distance from your house
and make sure that all your children understand that they
should go and wait for you if there is a fire.
Hold fire drills at least every 6 months to make sure that
everyone, even small children, know what to do to escape
safely.
Know where to go to call the fire department from outside your
residence.
Provide emergency equipment such as fire extinguishers and
teach your family to use this equipment properly.
d. Bedroom doors should be closed while sleeping if a smoke
alarm is installed in the bedroom. They act as a barrier
against heat and smoke.
WHAT TO DO IF THERE IS A FIRE
IN YOUR HOME
If you have prepared family escape plans and practiced them
with your family, you have increased their chances of escaping
safely. Review the following rules with your children when you have
fire drills so everyone will remember them in a real fire emergency.
If the alarm should sound:
a. Don't panic; stay calm. Your safe escape may depend on
thinking clearly and remembering what you have practiced.
b. Get out of the house following a planned escape route as quickly
as possible. Do not stop to collect anything or to get dressed.
c. Open doors carefully only after feeling to see if they are hot. Do
not open a door if it is hot; use an alternate escape route.
d. Stay close to the floor; smoke and hot gases rise.
e. Cover your nose and mouth with a cloth, wet if possible, and take
short, shallow breaths.
f. Keep doors and windows closed unless you open them to
escape.
g. Meet at your prearranged meeting place after leaving the house.
h. Call the Fire Department as soon as possible from outside your
house. Give the address and your name.
i. Never re-enter a burning building.
Contact your local Fire Department for more information on making
your home safer from fires and about preparing your family's escape
plans.
NOTE: Current studies have shown smoke alarms may not
awaken all sleeping individuals, and that it is the responsibility
of individuals in the household that are capable of assisting
others to provide assistance to those who may not be
awakened by the alarm sound, or to those who may be
incapable of safely evacuating the area unassisted.
WHAT THIS SMOKE ALARM
CAN DO
This smoke alarm is designed to sense smoke entering its
sensing chamber. It does not sense gas, heat, or flames.
When properly located, installed, and maintained, this smoke
alarm is designed to provide early warning of developing fires at a
reasonable cost. This smoke alarm monitors the air and, when it
senses smoke, activates its built-in alarm horn. It can provide
precious time for you and your family to escape from your residence
before a fire spreads. Such an early warning, however, is possible
only if the smoke alarm is located, installed, and maintained as
specified in this User's Manual.
NOTE: This smoke alarm is designed for use within single
residential living units only; that is, it should be used inside a single-
family home or one apartment of a multi-family building. In a multi-
family building, the smoke alarm may not provide early warning for
residents if it is placed outside of the residential units, such as on
outside porches, in corridors, lobbies, basements, or in other
apartments. In multi-family buildings, each residential unit should
have smoke alarms to alert the residents of that unit. Smoke alarms
designed to be interconnected should be interconnected within one
family residence only; otherwise, nuisance alarms will occur when a
smoke alarm in another living unit is tested.
IMPORTANT NOTE: WHAT SMOKE
ALARMS CANNOT DO
Smoke alarms will not work without power. A battery must be
connected to the smoke alarm to maintain proper device operation if
AC power supply is cut off by an electrical fire, an open fuse or
circuit breaker, or for any other reason. In the event of AC power
failure, the battery will supply standby power for a minimum of 24
hours.
Smoke alarms may not sense fire that starts where smoke
cannot reach the devices such as in chimneys, in walls, on roofs,
or on the other side of closed doors. If bedroom doors are usually
closed at night, smoke alarms should be placed in each bedroom as
well as in the common hallway between them.
Smoke alarms also may not sense a fire on another level of
a residence or building. For example, a second-floor smoke alarm
may not sense a first-floor or basement fire. Therefore, smoke
alarms should be placed on every level of a residence or
building.
The horn in your smoke alarm meets or exceeds current audibility
requirements of Underwriters Laboratories. However, if the smoke
alarm is located outside a bedroom, it may not wake up a sound
sleeper, especially if the bedroom door is closed or only partly open.
If the smoke alarm is located on a different level of the residence
than the bedroom, it is even less likely to wake up people sleeping in
the bedroom. In such cases, the National Fire Protection
Association recommends that the smoke alarms be interconnected
so that a device on any level of the residence will sound an alarm
loud enough to awaken sleepers in closed bedrooms. This can be
done by installing a fire-detection system, by connecting smoke
alarms together, or by using radio frequency transmitters and
receivers.
All types of smoke alarm sensors have limitations. No type
of smoke alarm can sense every kind of fire every time. In
general, smoke alarms may not always warn you about fires
caused by violent explosions, escaping gas, improper storage
of flammable materials, or arson.
NOTE: This smoke alarm is not designed to replace special-
purpose fire detection and smoke alarm systems necessary to
protect persons and property in non-residential buildings such as
warehouses, or other large industrial or commercial buildings. It
alone is not a suitable substitute for complete fire-detection systems
designed to protect individuals in hotels and motels, dormitories,
hospitals, or other health and supervisory care and retirement
homes. Please refer to NFPA 101,The Life Safety Code, and NFPA
72 for smoke alarm requirements for fire protection in buildings not
defined as "households."
Installing smoke alarms may make you eligible for lower
insurance rates, but smoke alarms are not a substitute for
insurance. Home owners and renters should continue to insure
their lives and property.
Pg. 7-2
PLACEMENT OF SMOKE ALARMS
THIS EQUIPMENT SHOULD BE INSTALLED IN ACCORDANCE
WITH THE NATIONAL FIRE PROTECTION ASSOCIATION'S
STANDARD 72 (National Fire Protection Association, Batterymarch
Park, Quincy, MA 02269).
For your information, the National Fire Protection Association's
Standard 72, reads as follows:
Smoke alarms shall be installed outside of each separate sleeping
area in the immediate vicinity of the bedrooms and on each
additional story of the family living unit including basements and
excluding crawl spaces and unfinished attics. In new construction, a
smoke alarm shall be installed in each sleeping room.
Where to Locate the Required Smoke Alarms in Existing
Construction. The major threat from fire in a family living unit is at
night when everyone is asleep. The principal threat to persons in
sleeping areas comes from fires in the remainder of the unit;
therefore, a smoke alarm(s) is best located between the bedroom
areas and the rest of the unit. In units with only one bedroom area
on one floor, the smoke alarms should be located as shown in Figure
1.
Figure 2: IN FAMILY LIVING UNITS WITH MORE THAN ONE
SLEEPING AREA, A SMOKE ALARM SHOULD BE PROVIDED TO
PROTECT EACH SLEEPING AREA (IN ADDITION, FIGURE 2
SHOWS REQUIRED SMOKE ALARMS IN EACH BEDROOM FOR
NEW CONSTRUCTION).
In addition to smoke alarms outside of the sleeping areas, NFPA
72 requires the installation of a smoke alarm on each additional story
of the family living unit, including the basement. These installations
are shown in Figure 3. The living area smoke alarms should be
installed in the living room or near the stairway to the upper level, or
in both locations. The basement smoke alarm should be installed in
close proximity to the stairway leading to the floor above. When
installed on an open joisted ceiling, the smoke alarm should be
placed on the bottom of the joists. The device should be positioned
relative to the stairway so as to intercept smoke coming from a fire in
the basement before the smoke enters the stairway.
Figure 4: RECOMMENDED SMOKE ALARM MOUNTING
LOCATIONS.
Figure 5: RECOMMENDED SMOKE ALARM LOCATION IN
ROOMS WITH SLOPED, GABLED, OR PEAKED CEILINGS.
The placement of the smoke alarm is critical if maximum speed of
fire detection is desired. Thus, a logical location for a smoke alarm
is the center of the ceiling. At this location, the device is closest to
all areas of the room.
WHERE SMOKE ALARMS SHOULD
BE PUT IN MOBILE HOMES
In mobile homes built after about 1978 that were designed and
insulated to be energy-efficient, smoke alarms should be installed as
described in the section above. In older mobile homes that have little
or no insulation compared to today's standards, uninsulated metal
outside walls and roofs can transfer heat and cold from outdoors,
making the air right next to them hotter or colder than the rest of the
inside air. These layers of hotter or colder air can prevent smoke
from reaching a smoke alarm. Therefore, put smoke alarms in such
units only on inside walls, between 4 and 12 inches (10 and 30 cm)
from the ceiling. If you are not sure about the insulation level in your
mobile home, or if you notice that the walls or ceiling are unusually
hot or cold, put the smoke alarm on an inside wall.
Minimum protection requires one smoke alarm as close to the
sleeping area as possible. For better protection, put one smoke
alarm in each room, but first read the "Locations to Avoid."
Figure 1: A SMOKE ALARM SHOULD BE LOCATED BETWEEN
THE SLEEPING AREA AND THE REST OF THE FAMILY LIVING
UNIT.
In family living units with more than one bedroom area or with
bedrooms on more than one floor, more than one smoke alarm will
be needed, as shown in Figure 2.
Figure 3: A SMOKE ALARM SHOULD BE LOCATED ON EACH
STORY.
Where to Locate the Required Smoke Alarms in New
Construction. All of the smoke alarms specified for existing
construction are required, and, in addition, a smoke alarm is required
in each bedroom.
Are More Smoke Alarms Desirable? The required number of
smoke alarms may not provide reliable early warning protection for
those areas separated by a door from the areas protected by the
Pg. 7-3
required devices. For this reason, it is recommended that the
householder consider the use of additional smoke alarms for those
areas for increased protection. The additional areas include:
basement, bedrooms, dining room, near furnace room, utility room
and hallways not protected by the required smoke alarms. The
installation of smoke alarms in kitchens, attics (finished or
unfinished), or garages is not normally recommended, as these
locations occasionally experience conditions that can result in
improper operation.
IMPORTANT CONSIDERATION
We recommend replacing your smoke alarm(s) every ten (10)
years; why:
Dust, dirt, and other environmental contaminants can affect your
smoke alarm over a prolonged period.
Fast changing industry consensus standards and codes on all
smoke alarms make it advisable to periodically upgrade your
device to maximize life safety.
Assurance that your smoke alarm needs are kept abreast with the
constantly improving electronic technology.
Smoke alarms are recognized as one of the lowest cost ways to
protect dwelling inhabitants against the danger of fire(s). It makes
good common sense to periodically replace and update your
smoke alarm that contributes so much to life safety.
MOUNTING LOCATION
Ceiling location (CS & CSX only) - smoke alarm should be
mounted as close as possible to the center of a hallway or room.
If this is not possible, the edge of the unit should be at least 4
inches from any wall.
Wall location-locate the top of the smoke alarm at least 4 inches
and not more than 12 inches from the ceiling. Observe smoke
alarm for proper top/bottom orientation (test knob is near bottom
of unit).
LOCATIONS TO AVOID
Nuisance alarms are caused by placing smoke alarms where
they will not operate properly. To avoid nuisance alarms, do not
place smoke alarms:
In or near areas where combustion particles are normally
present such as kitchens; in garages where there are particles
of combustion in vehicle exhausts; near furnaces, hot water
heaters, or gas space heaters. Install smoke alarms at least
20 feet (6 meters) away from kitchens and other areas where
combustion particles are normally present.
In air streams passing by kitchens. Figure 6 shows how a
smoke alarm can be exposed to combustion particles in normal air
movement paths, and how to correct this situation.
Figure 6.
3. Metal outlet boxes must be grounded to earth ground.
4. Use only Duracell MN 1604 battery with the 7109/7139 Series
smoke alarms.
CAUTION: Turn off electricity to prevent SHOCK and damage to
smoke alarm. Be sure the power line to device is not controlled by
any on/off switch, or other type of switch, other than a fuse or circuit
breaker.
IMPORTANT: Insure that all fluorescent lighting fixtures are properly
grounded or on separate circuits.
WARNING: Smoke alarm installation must conform to the electrical
codes in your area and to Article 760 of the U.S. National Electrical
Code. Wire installation should be performed only by a licensed
electrician.
MOUNTING OUTLET BOX
(7109CS/CSX & 7139CS/CSX only)
Use a 2" x 3" switch box or a 4" square or octagon junction box.
Mount a box for each smoke alarm. If wall mounting is desired, be
sure the box screws are oriented to upper right and lower left
corners. Be sure to use supplied Mounting Plate.
NOTE: For trouble areas where there can be a large volume of
air blowing out through the electrical junction box. You must first
attach an adhesive backed foam gasket, which has been packed
with your smoke alarm, to the back side of the mounting bracket
before it's secured to the junction box.
WIRING ONE SMOKE ALARM
(7109CS/CSX & 7139CS/CSX only)
1. Run a minimum of 16 gauge, 2-conductor cable, plus ground (3
wires) to the device junction box from a power supply. Smoke
alarms should be run on their own dedicated circuit. Use U.L.
listed Class 1 wire.
NOTE: The wiring to be used shall be in accordance with the
provisions of Article 210 of the National Electrical
Code, ANSI/NFPA 70.
2. Make wire connections to the supplied plug-in connector as
follows: black to black, white to white, and connect the ground
wire to the metal outlet box.
Figure 7
NOTE/RED-YELLOW WIRE: The red-yellow wire from the smoke
alarm is for tandem connection only. DO NOT USE, AND DO NOT
REMOVE INSULATION CAP UNLESS CONNECTING ANOTHER
SMOKE ALARM.
Figure 8
In damp or very humid areas, or next to bathrooms with
showers. The moisture in humid air can enter the sensing
chamber as water vapor, then cool and condense into droplets that
cause a nuisance alarm. Install smoke alarms at least 10 feet (3
meters) away from bathrooms.
In very cold or very hot environments, or in unheated
buildings or outdoor rooms, where the temperature can go
below or above the operating range of the device. Temperature
limits for proper operation are 40° to 100°F (4.4° to 37.8°C).
In very dusty or dirty areas. Dust and dirt can build up on the
smoke alarm's sensing chamber and can make it overly sensitive,
or block openings to the sensing chamber and keep the smoke
alarm from sensing smoke.
Near fresh air inlets or returns or excessively drafty areas. Air
conditioners, heaters, fans, and fresh air intakes and returns can
drive smoke away from smoke alarms, making the devices
less effective.
In dead air spaces at the top of a peaked roof or in the
corners between ceilings and walls. Dead air may prevent
smoke from reaching a smoke alarm.
In insect-infested areas. If insects enter a smoke alarm's
sensing chamber, they may cause a nuisance alarm. Get rid of
the bugs before installing smoke alarms where bugs are a
problem.
Near fluorescent light fixtures. Electrical "noise" from nearby
fluorescent light fixtures may cause a nuisance alarm. Install
smoke alarms and fluorescent lights on separate electrical
circuits.
WARNING: Never remove power from smoke alarm to silence a
nuisance alarm. Open a window or fan air around device to remove
the smoke. The smoke alarm will automatically turn off when the
smoke in the air is completely gone. Do not stand close to device.
The sound produced by the smoke alarm is loud because it is
designed to awaken you in an emergency. Prolonged exposure to
the horn at a close distance may be harmful to your hearing.
BATTERY INSTALLATION
1. Remove smoke alarm from mounting plate by rotating counter-
clockwise.
2. Remove AC power connector and unsnap power leads from
top of the old battery. Snap new battery onto snaps and
reinsert battery through hole in back of smoke alarm.
3. Use only Duracell MN 1604 battery with the 7109/7139 Series
smoke alarms.
WARNING: Units with battery back-up will not provide power or
transmit an alarm to AC only units in the event of an AC
power failure.
All battery back-up units in tandem, with good batteries, will operate
normally during an AC power failure. NOTE: Strobe will not
operate during AC power failure.
WIRING/GENERAL
(7109CS/CSX & 7139CS/CSX only)
1. Use U.L. listed cable with Class 1 insulation.
2. Observe local code requirements. Use box connector to anchor
cable to outlet box.
WIRING TWO OR MORE SMOKE
ALARMS (7109CS/CSX & 7139CS/
CSX only) Tandem Installation
CAUTION: All smoke alarms in tandem installation must be
controlled by the same fuse or circuit breaker. Otherwise tandem
units will not operate. Tandem will operate in the event of AC power
failure if battery is connected to the smoke alarm.
Pg. 7-4
LIMITATIONS: A maximum of six (6) smoke alarms of model
(7109CS/CSX & 7139CS/CSX or models with the relay option (F, HF,
TF) may be tandem interconnected. Do not exceed 1125 feet
between first and last smoke alarm.
Wire used for interconnecting shall be in accordance with the
latest edition of article 760 of the National Electrical Code (NEC),
and NFPA 70, and must not exceed a resistance of 10 ohms.
1. Run a minimum of 16 gauge, 3-conductor cable, plus ground
(4 wires) to the first junction box from a power supply and
between all smoke alarms that are to be connected together.
Use U.L. listed Class 1 wire.
2. Make wire connections to the supplied plug-in connector as
follows: black to black, white to white, 3rd conductor to the
red-yellow wire. The red-yellow wire should be stripped to
make this connection. Connect ground wire between metal
outlet boxes.

6. Remove smoke alarm from wash water and transfer directly to
one of the first rinse buckets containing clear water. Again, allow
smoke alarm to become completely submerged, agitate once
more for 5 or 10 seconds to remove soap residue.
7. Finally, transfer smoke alarm to your second and final rinse
bucket, repeating method found in Step 6, then remove smoke
alarm to a clean dry area for a period of 48 hours to allow it to
thoroughly dry.
WARNING: SMOKE ALARMS ARE TO BE AIR DRIED ONLY. DO
NOT PLACE DEVICE IN OVEN, MICROWAVE OR USE A HOT AIR
BLOWER TO ACCELERATE DRYING TIME. THIS COULD
RESULT IN DAMAGE TO YOUR SMOKE ALARM.
IMPORTANT: IT IS RECOMMENDED TO CHANGE WASH AND
RINSE WATER AFTER FIVE (5) SMOKE ALARMS. IF YOUR
DEVICES ARE EXTREMELY DIRTY, WATER SHOULD BE
CHANGED MORE FREQUENTLY.
In the event you experience difficulty in the cleaning of your
smoke alarm or if you have any questions, please contact Gentex
Corporation or your local Gentex distributor.
WARNING
If the smoke alarm does not work properly, do not try and fix it
yourself. This will void your warranty. See "To Return a Smoke
Alarm" for instructions to return smoke alarms that do not operate
properly. DO NOT TRY TO FIX IT YOURSELF.
IMPORTANT: Gentex recommends smoke alarm be tested a
minimum of once a week.
WARNING: Never use an open flame of any kind to test your
smoke alarm. You may ignite and damage the smoke alarm as well
as your home. The test feature of your smoke alarm accurately
simulates smoke conditions and tests the smoke alarm's functions as
required by Underwriters Laboratories.
WARNING: Do not cover, tape, or otherwise block the openings
of your smoke alarm. These openings are designed to allow air to
pass through your smoke alarm, thus sampling the air around the
device.
WARNING: Smoke alarms are not to be used with detector
guards unless the combination has been evaluated and found
suitable for that purpose.
FAILURE TO REGULARLY CLEAN THIS SMOKE ALARM WILL
RESULT IN FALSE ALARMS. A BUILD UP OF DUST CREATES AN
OBSCURATION THAT SIMULATES SMOKE. THIS MEANS THE
UNIT WILL GO INTO ALARM WITHOUT A FIRE CONDITION.
TO RETURN A SMOKE ALARM
Should you experience problems with your smoke alarm, proceed
as follows:
1. Rotate the smoke alarm counter-clockwise to remove it from its
mounting plate.
2. Unplug the electrical power cord to the smoke alarm and remove
the battery. Do not ship smoke alarm with battery installed.
3. Carefully pack (the manufacturer cannot be responsible for
consequential damage) and return to the manufacturer. Include
complete details as to exact nature of difficulties being
experienced and date of installation.
4. Return to: Gentex Corporation, 10985 Chicago Drive, Zeeland,
Michigan 49464. Prior to returning, call Gentex at
1-800-436-8391 or e-mail [email protected] to obtain a
RMA Number from our return department.
c. To test smoke alarm for high sensitivity, turn test knob
clockwise to TEST 2 position. Smoke alarm should remain
silent. Return knob back to the normal position. If your
smoke alarm sounds during this test it means the device’s
sensitivity has become too high and may cause false alarms.
This could mean your smoke alarm is dirty and should be
cleaned as described in the maintenance procedure below. If
the smoke alarm continues to alarm for TEST 2 position
following cleaning return it to Gentex for service.
d. To check for proper smoke entry into your smoke alarm's
sensing chamber. Gentex recommends using the Home
Safeguard Smoke Alarm spray. This test should be
performed once a year and should be sprayed from a
distance no closer than 12 inches from smoke alarm.
MAINTENANCE
After your smoke alarm has been in operation for a period of time
or if it was installed prior to the completion of all building
construction, your smoke alarm may have become more sensitive
due to dirt build-up in the smoke alarm's optic sensing chamber
which could cause nuisance alarms or could cause activation from
small amounts of smoke build-up.
If this should occur, following this simple washing procedure will
restore your smoke alarm back to its original condition.
For further information, regarding frequency of cleaning and test-
ing, refer to NFPA 72, NFPA, Batterymarch Park, Quincy, MA 02269.
IMPORTANT: Failure to follow full cleaning instructions
could result in damage to this smoke alarm. DO NOT remove
all smoke alarms at the same time for cleaning.
1. Rotate the smoke alarm counter-clockwise to remove it from its
mounting plate.
2. Unplug the electrical power cord to the smoke alarm and remove
the battery.
3. Select three (3) standard size wash buckets and fill them each
with one gallon of normal tap water (distilled or de-ionized treated
water is recommended as a final rinse if water is extremely hard
in your area).
4. Add 1/8 cup of Ivory dishwashing liquid to the first bucket of
water and allow it to mix thoroughly, then place one dirty smoke
alarm into the soap water mixture until it becomes completely
covered or submerged. NOTE: If the smoke alarms are
exceptionally dirty, you may wish to first wipe off any excess dirt
before washing smoke alarm so as not to dirty the wash water
too quickly.
DO NOT open smoke alarm for cleaning. IF SMOKE ALARM IS
OPENED, PRODUCT WARRANTY BECOMES VOID.
WARNING: ONLY IVORY DISHWASHING LIQUID IS TO BE USED.
OTHER BRANDS ARE NOT RECOMMENDED AND
MAY CAUSE YOUR SMOKE ALARM TO
MALFUNCTION.
5. Allow smoke alarm to soak for approximately 10 minutes (longer
if extremely dirty). Then agitate for 5 or 10 seconds to flush out
any remaining dirt left inside smoke alarm's housing.
